Example of Brown Spot Fungus

Lawn fungal disease can take on a variety of forms, all of which can be found within the lawns soil. Several outside factors can bring many different fungi which can adversely affect your lawn. Over the past few seasons, we have seen an increase in disease pressure. This is because of the ideal environmental conditions which have favored disease development. A variety of diseases can seriously affect the appearance of your lawn. If not treated, fungus can create brown spots, inhibit growth, and in worst cases destroy your lawn. In general, by the time you recognize you have a problem, it is too late. After investing thousands of dollars and quality time to have a beautiful lawn, one summer of disease can destroy what you have worked hard to achieve.

Educate yourself:

  • There is no rhyme or reason why one property does or does not have fungal issues.
  • Typically, fungus is not prevalent in lawns until end of May or first of June. depending on the season.
  • Lawn fungus can show up in the same spot year after year.
  • Fungus looks like the lawn is dry and adding more water can exacerbate the problem.

Fungus Factors:

  • Irrigation Suggestions
    • Early morning, before 5am, is optimal; late evening, after 7pm, is alright.
    • Don’t irrigate middle of the day, 8am till 7pm.
    • Prevent saturation of the lawn by monitoring how long zones run.
    • Work with irrigation company for best advice based on your individual lawn.
    • If rain has been consistent, turn off irrigation to prevent saturation.
  • Mowing or mowers
    • Mowers can transfer fungus and track disease throughout your lawn. This usually looks like brown tire tracks.
    • However, this is out of mowing companies’ control.
    • Ideal mowing height is 3.5-4 inches.
    • Mower blades should be sharp and clean to prevent spreading disease.

Our Products:

  • Unfortunately, disease management products are costly.
  • Disease pressure is out of our control, and depending on outside factors, can still be a problem even with fungicide applications.
  • Our disease management program is designed to work as a preventative as well as a curative treatment to help maintain the health and vitality of your lawn.
  • Depending on the fungus pressure severity, some lawns may require an additional treatment for fungus outside of the three applications offered under our fungicide option.
  • After an application, it will take some time for the lawn to recover. It’s important to note that curative applications do not reverse the effects of already sick tissues (yellow or brown individual blades). These applications are only designed to protect uninfected and new growth that hasn’t been struck by the disease.

Our fungicide program is designed to work as a preventative and curative treatment to help maintain the health and vitality of your lawn. While curative treatments are available, prevention is vital. Curative applications do not reverse the effects of an already diseased lawn (yellow or brown individual blades). These applications are only designed to protect uninfected and new growth. Therefore, preventative applications are key in maintaining your lawns health. Our fungicide program includes three treatments over the summer months of June, July and August when disease pressure is the highest. This program is specifically designed to coincide with the 6-step lawn program and is a central element in keeping your lawn healthy.

With the changing weather patterns and the increase in disease pressure, this application is vital to maintain your lawns health.

    Thanks for the detailed fungus information. My lawn has suffered from this in the past years even with fungicide treatments from my previous lawn maintenance company (Lawns Unlimited)
    I’m hoping and praying the product you use is better and you guys can get it protected for me ASAP, as we are already in the 2nd week of June.
    Looking forward to a call soon to inform us you are on your way to Milton to apply the first treatment. I will mow lawn tall prior to your arrival so it won’t have to be mowed after the application
    Thanks again. Looking forward to working wil you guys and keeping my lawn lush and GREEN

    Should the irrigation system be turned off for 2 days after the fungicide is applied? What happens if the lawm is mowed 10 hours after the fungicide was applied?
